Description

• When a custom event with multiple days is exported in an ics file, multiple copies of it are created.
• Below is the relevant excerpt from an exported file containing one custom event repeating on Sunday and Monday.

Reproduction

• Create a custom event repeating on multiple days.
• Download the ics file.
• Inspect it manually or import it into a calendar app.

Diagnosis

• It's probably to do with how multiple events are created for class sections that meet multiple times.
  • I think this is the case because class sections can meet in different places throughout the week.
• The fix likely involves either creating only one event repeating on multiple days for custom events (preferable) or creating one custom event for each day.
